The polarity (+/-) was reversed when I made a measurement using the resistance range. Is the instrument broken?

QI have a question about an analog tester. The polarity (+/-) is reversed when performing measurements with the resistance range. Why is this? Wouldn’t this invite mistakes, for example when checking diode polarity?

A

Inability to start a withstanding test

QWhen I try to start the test, measurement does not start.

A

Infrared thermometer measurable temperature range

QHow far away can an infrared thermometer take readings?

A

Clamp sensor voltage to earth

QThe specifications for the Clamp On Leak HiTester 3283 indicate a maximum rated voltage to earth of 300 V rms AC (insulated conductor) (CAT III, 300 V). Can the 3283 be used to measure a 3-phase 400 V circuit?

A

Display of measurement data in a format such as “1.05E+02”

QWhen I used Excel to view measurement data recorded onto a PC card with a clamp-on power meter, the voltage U1 was displayed in a format such as “1.05E+02.”

A

Loss due to the instrument connection method

QDo measured values vary with the power meter connection?

A

Error upon connection check

QThe instrument indicates an error when it checks the connection, even though it is connected properly.

A

How do I record a 4 to 20 mA instrumentation signal?

QI’d like to record a 4 to 20 mA measurement signal with my Memory HiLogger, but the instrument lacks a suitable measurement range. Is there a method I can use to record this signal?

A

Measurement of the secondary side of an inverter

QWhat type of instrument should I use to measure an inverter’s current and voltage?
